Research case

“Synthetic replacements for human survey data?” (Bisbee et al., Political Analysis 2024)

Political scientists asked ChatGPT to answer ANES feeling-thermometer questions as demographic personas and compared the results with real respondents.

What is reported

Averages looked close, but synthetic answers had far less variance, regressions often led to different conclusions, and results shifted with prompt wording and over three months.

Before you use it

A key counterweight to silicon-sample enthusiasm; read it before using simulated respondents for anything beyond pretesting.
